Muon tracks have undefined LHCbIDs

This is a follow up to #793 (comment 8131211)

Tracks like

*** Track ***
 key        : 128
 type       : Unknown
 history    : Unknown
 fitstatus  : Unknown
 # ids      : 4 [ { LHCbID :  } { LHCbID :  } { LHCbID :  } { LHCbID :  } ]
 # VP clus  : 0
 # UT clus  : 0
 # FT clus  : 0
 chi2PerDoF : 0
 nDoF       : 0
 GhostProb  : 999
 Likelihood : 999
 extraInfo : []
 # states : 0

where reported there.

I have checked to see why the LHCbIDs are not showing anything useful. The issue is not a printing issue, but these LHCbIDs are indeed undefined. I extended the LHCbID printout to check for this and now I see

*** Track ***
 key         : 59
 type        : Unknown
 history     : Unknown
 fitstatus   : Unknown
 LHCbIDs     : 4 [ { LHCbID : UNDEFINED } { LHCbID : UNDEFINED } { LHCbID : UNDEFINED } { LHCbID : UNDEFINED } ]
 VP clusters : 0
 # UT clus   : 0
 # FT clus   : 0
 chi2PerDoF  : 0
 nDoF        : 0
 GhostProb   : 999
 Likelihood  : 999
 extraInfo   : []
 # states    : 0

The UNDEFINED means the LHCbID do not have any sub-system type set. I now explicitly check for this and print UNDEFINED when this is the cause.

@mveghel Please take a look. Either the issue is happening when you clone the IDs into these 'tracks' or the original IDs from the Muon reco does not have them correctly set.
